  • Patent number: 9498758
    Abstract: A dilution apparatus includes a container having an adjustable float-operated make-up valve wherein the make-up valve has an inlet end connected to a water supply tube and an outlet end connected to a fill tube inside the container. The make-up valve is connected to a float disposed inside the container. The water supply tube is connected to a reservoir that contains a concentrate. The water flow through the water supply tube siphons the concentrate, into the water stream and through the make-up valve to form a first dilution. A proportioner is connected to a water supply and to the bottom of the container. The water flow through the proportioner siphons the first dilution into the proportioner, thereby mixing the first dilution with water to form a final product having a predetermined dilution ratio.

  • Publication number: 20130156907
    Abstract: A process for sanitizing objects is comprised of the steps of: (1) contacting the object with a dry fog in an enclosed sanitization zone wherein the dry fog is comprised of droplets having a diameter of 4-5 microns and wherein the droplets comprise an aqueous solution of a sanitizing agent for a time sufficient to produce a substantially dry sanitized object and a residual amount of dry fog; (2) removing the substantially dry, sanitized product from the enclosed zone while simultaneously removing the residual dry fog and passing the residual dry fog through a treatment zone whereby unreacted sanitizing agent is removed from the dry fog. The disclosed process yields substantially dry sanitized objects that do not require rinsing with water.

  • Patent number: 6842283
    Abstract: An apparatus for generating variable DGD is particularly for use in a PMD compensator. The apparatus has first, second and third birefringent elements arranged in order between the input and output of the compensator and having first, second and third differential group delays (DGDs) in the ratio 1:2:1. The orientation of the PSPs of the signal in each element relatively to the principal axes of the element is controlled, such that a change in orientation between the first and second elements is equal and opposite to a change in orientation between the second and third elements. This arrangement provides symmetrical relative rotations of the signal PSPs and principal axes about the central birefringent element. In combination with the 1:2:1 ratio, it can be shown that compensation of any first order PMD can be achieved without the compensator introducing additional second order PMD. The required level of first order PMD compensation is selected by controlling the amount of the orientation changes.

  • Patent number: 6597495
    Abstract: An improved method is provided for reducing four-wave mixing induced degradation in an optical data signal traversing an optical transport network that uses Raman amplifiers. The method includes: introducing at least two Raman amplifiers into the optical transport network, each Raman amplifier having a laser source, and synchronously modulating the laser sources of the Raman amplifiers, thereby reducing four-wave mixing in the optical data signal. Modulation of the laser sources is performed at such a rate that crosstalk from the modulation to the optical data signals experiencing the Raman gain is minimized.
